10PCS LM4863D DIP16 LM4863 DIP-16 4863D Audio Amplifier IC

here's the design that I came up with by looking at Oh some other examples but there's one resistor the one at the lower left question mark okay what I'm going to do here is I've got a variable resistor at this point and I'm going to change the variable resistor until the signal that I put in will when I overdrive this by the way with the signal it bottoms out and also flat tops approximately at the same time the red arrow is where I have the oscilloscope connected and I did change the variable resistor and change the input over driving it until as you can see it flat tops and bottoms out approximately at the same time I have removed the variable resistor and now I'm measuring what that resistance is and it's 1089 ohms I don't have that I do have a thousand ohms and this one reads 989 ohms so I have installed that in the circuit and I'm going to hook the scope back up and we'll take a l
